' To all whom it may concern:

Be it known that we, MAX BLUM and JA- COB STEIN, citizens of the UnitedStates, residing at Elizabethport, in the State of New Jersey, haveinvented certain new and useful Improvements in Rope-Clamps; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference bein had to theaccompanyin drawings, and to letters of reference marked thereon, whichform a part of this specification.

Our invention'relates to a rope clamp and I one that is designed moreparticularly for the tightening of rope, such as pulley lines andclothes lines, and the invention is of a class that employs tapered jawssliding in a cylindrical sleeve so that a greater strain on the Thisinvention is desi ned to rovide an article of this kind wit shoul ers onthe i i front, and to limit the movement of the gripping jaws and toform bearings for the fin ers to hold the jaws back, when it is desireto let them e sli through the aws. -A furtl ier o ject is to providethese jaws with ribs on their interior surfaces for engagement with therope.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side view of the device. Fig.

' 2 is ato view, and Fig. 3 is a section on line 3, 3, in *ig. 1. Fig. 4is a face view of the inside of one of the jaws.

In the drawings, the body portion 10 has the eye 1 1 in one end for thereception of one end of a rope 12. This body portion has, also, thebulgin portions 13 ending up on the lie cylindrical part 14. Secured inthe cylindrical part are the two jaw sections 15, which are formed withthe shoul- (lers 16 on the small end to limit the backward movement ofthe jaws, and to provide finger pieces for holding them back. These jawshave the same interior diameter for their full length, but theirexterior tapers, and have the enlarged end 17. It will thus be seen thata pull on the rope away from the body portion, will tend to grip therope and secure it. To more securely hold the said rope, we prefer torovidethe interior of the jaws with a series 0? ribs 18, of any usualconstruction, these jaws grip ing the end 19 of the rope and assuring nos i ping.

Between the eye 11, an the cylindrical part 14 is arranged a ring orannular portion 20 which may be integral with the body portion. Theoffice of this ring is to guide the rope, so that when the end 19 ispulled, even although the pull is not directly in line with the axis ofthe jaws, then the rope will not be jammed or forced between the aws 15at their sides. This might easily result, if the rin was absent, as therope would act as a we geto force itself-in between the jaws, if therewas-a distinct side pull on the free end 19 of the r0 e.

Having t 'us described our invention, what we claim 1s:

A device of the kind described, comprising a body-portion having bulgingside pieces, an eye on one end of the body portion and a cylindricalpart on the other end, the eye forming means for attachin one end of arope, a air of tapered jaws s iding in the cylindrica part, for raspingthe en of a rope, and a ring secured to the side pieces and in line withthe jaws to guide the free end of the rope and prevent the entrance ofthe rope between the sides of the jaws.

In testimony, that we claim the fore oing, we have hereunto set ourhands this 28t day of March1906.

MAX BLUM. JACOB STEIN.
